THE ROCK KEY Use this key to ask and answer questions on your unknown rock specimens. The key can help guide you to the correct rock identification. 1. Is the rock made of crystal grains? (Does it have a lot of flat, shiny faces – may be tiny or small - that reflect light like little mirrors? You may need to use a magnifier.)File Size: KB.

A great book for reading or reference, this handy (" x ") handbook by Chris Pellant presents interesting facts with full-color photos of hundreds of different rocks and minerals. Contains pages, a glossary, identification guides and index. Grain Size: Coarse grains are visible to the naked eye, and the minerals can usually be identified without using a magnifier. Fine grains are smaller and usually cannot be identified without using a magnifier.; Hardness: This is measured with the Mohs scale and refers to the minerals contained within a rock. In simple terms, hard rock scratches glass and steel, usually signifying the Author: Andrew Alden. One meteorite testing laboratory a few years ago said that they received on average rock samples per year from persons who thought they had found a meteorite. On average there were only one or two real meteorites per year. With the wonderful media attention meteorite hunting has gotten in the last three or four years that facility had to.
